Is it possible to have more than 1 user log in to ArcGIS Online using the same account information at the same time?
Tim, might be good to mark the updated link, and Andrew's response in the link as correct. Looks like a very good answer to me for both questions. My opinion (even if I wish it wasn't the case).
I'm confused. What does Andrew mean when he says "authorization codes"? I help manage our 50 user ArcGIS Online for organizations and I'm unaware of any authorization codes for users.
